For rotating shafts that need reliable lubricant retention and contaminant exclusion, the DBH 5640 radial shaft seal is a single-lip, spring-loaded design. It fits a 45.80 mm shaft, a 66.57 mm housing bore, and a 12.70 mm height, making it a compact solution for tight installations. The seal presses into the housing while its flexible lip runs against the shaft, compensating for minor misalignment.

The DBH 5640 seal, part number 5640, is identified by three key dimensions: shaft diameter 45.80 mm, housing bore 66.57 mm, and overall height 12.70 mm. Its single-lip configuration with a spring provides a dynamic seal on the shaft and a static seal in the housing. The 12.70 mm height allows installation in shallow cavities without compromising sealing performance.

You will find this seal in gearboxes, pumps, electric motors, reducers, and other power transmission equipment. Its role is to keep oil or grease in and keep dust, water, and particles out, protecting bearings and gears from premature wear. The compact size suits spaces where larger cross-section seals will not fit, and it is a practical choice for industrial machinery and process equipment.

Selection requires matching the shaft and housing dimensions to the seal. Confirm the shaft diameter is within the recommended tolerance and the housing bore is 66.57 mm with adequate depth for the 12.70 mm height. A proper surface finish on the housing helps ensure a good static seal. During installation, lubricate the lip, use a suitable tool, and press the seal in perpendicular to the shaft without striking it directly.
